+### Contents
+
+This directory contains all the glyphs (glyph sets) that the `font-patcher` puts into the fonts.
+
+If a icon font here is updated, do not forget to update the database file in `bin/script/libs`.
+
+The 'Seti and Original' icons (in `original-source.otf`) is automatically generated from the glyphs in `src/svgs`.
+Do not edit and commit changes to that font directly.

+## Contents
+
+This folder contains the source for the (current) Material Design Icons.
+Source is https://github.com/Templarian/MaterialDesign-Font
+
+Last fetch date is Oct 6, 2022.
+
+After fetching a new file one needs to correct our cheat-sheet by updating `bin/scripts/lib/i_md.sh`.
+Use the tool:
+```
+cd bin/scripts
+mv lib/i_md.sh lib/i_md.sh_
+python3 generate-glyph-info-from-set.py --start f0001 -end f1af0 -font ../../src/glyphs/materialdesign/MaterialDesignIconsDesktop.ttf -offset 0 -prefix md > lib/i_md.sh
+```
+
+Open old and new definitions shell script and copy the header from the old file to the autogenerated file. Adapt the values in the new file's header. Remove the last line in the new file (it contains the number of glyphs that is needed for the updated header). Yes, that is some manual labor.
+
+
+## Source bugs fixed
+
+Glyph 0xF1522 is broken in the original font. We fixed that one glyph manually.
+
+See https://github.com/Templarian/MaterialDesign-Font/issues/9
